turned from ON/RUN to LOCK/OFF,the windows and sunroof continueto work up to 10 minutes or until anydoor is opened. The radio continuesto work for up to 10 minutes or untilthe driver door is opened.
Accessory Power Outlets (APOs)
The vehicle may have AccessoryPower Outlets (APOs) in severallocations. SeePower Outlets0124.
The APOs in the console or centerseat position are powered byRetained Accessory Power (RAP).They will continue to work for up to10 minutes after the key is turnedfrom ON/RUN to LOCK/OFF, or untilthe driver door is opened.
The APOs on the center stack comefrom the factory powered directlyfrom the vehicle battery, and supplyaccessory power at all times,regardless of ignition key position.
If electronic items are left pluggedinto these APOs for long periods oftime with the vehicle off, the vehiclebattery could be drained. Thevehicle may not start if the battery isallowed to drain for an extendedperiod of time.
Engine Coolant Heater
The engine heater can provideeasier starting and better fueleconomy during engine warm-up incold weather conditions at or below✓18 °C (0 °F). Vehicles with anengine heater should be plugged inat least four hours before starting.An internal thermostat in theplug-end of the cord may exist,which will prevent engine coolantheater operation at temperaturesabove✓18 °C (0 °F).
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap theelectrical cord. The cord issecured to the driver sidefender with a clip, next to theengine compartment fuseblock. Carefully remove thewire tie that bundles theelectrical plug. Do not cut theelectrical cord.
Check the heater cord fordamage. If it is damaged, donot use it. See your dealer forareplacement.Inspectthecord for damage yearly.
3. Plug the cord into a normal,grounded 110-volt AC outlet.

Passing
More passing distance is neededwhen towing a trailer. Thecombination will not accelerate asquickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.
Backing Up
Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.
Making Turns
Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike softshoulders, curbs, road signs, trees,or other objects. Avoid jerky orsudden maneuvers. Signal well inadvance.
If the trailer turn signal bulbs burnout, the arrows on the instrumentcluster will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.
Driving on Grades
Reduce speed and shift to a lowergearbeforestarting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might get hot and no longerwork well.
Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear ifthe transmission shifts too oftenunder heavy loads and/or hillyconditions.
The Tow/Haul Mode may be used ifthe transmission shifts too often.SeeTo w / H a u l M o d e0282.
When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boil atalowertemperaturethanatnormalaltitudes. If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle may show signs similar toengine overheating. To avoid this,let the engine run while parked,preferably on level ground, with thetransmission in P (Park) for a fewminutes before turning the engineoff. If the overheat warning comeson, seeEngine Overheating0372.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.

Caution (Continued)
damaged if either the front or rear
axle ratings or the Gross Vehicle
Weight Rating (GVWR) are
exceeded.
The plow the vehicle can carrydepends on many things, such as:
.The options the vehicle camewith, and the weight of thoseoptions.
.The weight and number ofpassengers to be carried.
.The weight of items added to thevehicle, like a tool box ortruck cap.
.The total weight of anyadditional cargo to be carried.
For example, if the snow plowweighs 318 kg (700 lb), the totalweight of all occupants and cargoinside the cab should not exceed135 kg (300 lb). This means that youmay only be able to carry onepassenger. Even this may be too
much if there is other equipmentalready adding to the weight of thevehicle.
To s a f e l y c a r r y a s n o w p l o w o n t h evehicle:
.Follow all aftermarket snow plowmanufacturer’sinstructionsforthe operation and transportationof the snow plow.
.With a snow plow attached, theengine coolant temperaturegauge may show a highertemperature than while drivingwithout one. The snow plowcould block the airflow to theradiator. This could be morenoticeable as vehicle speedincreases. At speeds above72 km (45 mph), this may causethe engine coolant to overheat.
.To i n c r e a s e t h e a i r f l o w, m o v e t h esnow plow blade postion.
.If driving more than 24 km(15 mi), angle the plow bladeposition.
.Make sure the weight on thefront and rear axles does notexceed the axle rating for each.
.For the front axle, if more cargoor passengers must be carried,appropriate counter ballast mustbe installed rear of the rear axle.Counter ballast must be properlysecured so it will not moveduring driving.
.Rear ballast may be required toensure a proper front and rearweight distribution ratio, eventhough the actual weight at thefront axle may be less than thefront axle rating.
.The snow plow manufacturer orinstaller can assist indetermining the amount of rearballast required, to help makesure the snow plow/vehiclecombination does not exceedthe GVW rating, the front andrear axle ratings, and the frontand rear weight distribution ratio.
.The total vehicle must notexceed the GVW rating.

To e n s u r e p r o p e r e n g i n eperformance and long life, carefulattention must be paid to engine oil.Following these simple, butimportant steps will help protectyour investment:
.Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil”in this section.
.Check the engine oil levelregularly and maintain theproper oil level. See“CheckingEngine Oil”and“When to AddEngine Oil”in this section.
.Change the engine oil at theappropriate time. SeeEngine OilLife System0362.
.Always dispose of engine oilproperly. See“What to Do withUsed Oil”in this section.

4. Remove the four screws (1) ontop of the cover of the housingand lift up the cover.
5. Remove the engine air cleaner/filter from the housing. Takecare to dislodge as little dirt aspossible.
6. Clean the engine air cleaner/filter sealing surfaces and thehousing.
7. Inspect or replace the engineair cleaner/filter.
8. Reverse Steps 2–4toreinstallthe filter cover housing.
{Warning
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when you are driving.
Cooling System
If the vehicle has the Duramaxdiesel engine, see the Duramaxdiesel supplement.
The cooling system allows theengine to maintain the correctworking temperature.
